Abstract

Deeper understanding of the microstructure formation and evolution as a function of solidification settings may be attained by using Cu-mold rapid solidification as well as water-cooled directional solidification techniques. This is explained by the broad range of conditions which can be tested at this point. The examination of microstructure parameters such as grain size and morphology/distribution of the intermetallic particles is essential to comprehend application properties of the Mg-Si based alloys. The present project aims to evaluate the Mg-0.5wt.%Si, Mg-1.38wt.%Si (eutectic) and Mg-2.3wt.%Si alloys. Furthermore, Sr, Ca and Zn-containing Mg-Si alloys will be generated as ternary compositions of interest. For all examined alloys, it is expected to evaluate the effects of the microstructure features in the corrosion and mechanical resistances.
